Childhood asthma, food allergy may up anxiety disorder risk

Toronto, Jan 5: If your child is suffering from chronic illness such as asthma or food allergy, he or she is more likely to develop anxiety or other mental health disorders, finds a study

The findings showed that anxiety disorders were most common, including separation anxiety, generalised anxiety and phobias, in kids with chronic illness such as asthma, food allergy, epilepsy, diabetes or juvenile arthritis.

For the study, detailed in the journal BMJ Open, the team from the University of Waterloo surveyed children between the age of six and 16.

According to parents’ responses to a standardised interview, 58 per cent of children screened positive for at least one mental disorder.

Six months after diagnosis, the number of kids showing signs of a mental disorder dipped slightly to 42 per cent.

“These findings show that risk for mental disorder is relatively the same among children with different physical conditions,” said Mark Ferro, Professor at Waterloo.

“Regardless of their condition, children with physical and mental health problems experience a significant decline in their quality life within the first six months after receiving their diagnosis, indicating a need for mental health services early on,” Ferro added

The researchers found that age and gender had no impact on the results. A subset of kids self-reported on their own mental health.

Eating high-carb diet can help lose weight

New York, Sep 25: Struggling hard to shed those extra kilos? If so, foods high in carbohydrates — found in fruits, vegetables, whole grains, and legumes — may help you reduce body weight and fat as well as improve insulin function, suggests a study challenging previous beliefs.

It is because these complex carbohydrates are naturally rich in fibre — a nutrient found in plant foods that adds bulk to the diet without adding extra calories.

The study, led by US-non-profit Physicians Committee for Responsible Medicine, showed that a plant-based, high-carbohydrate diet can help with weight regulation and body composition and reduce the risk for Type-2 diabetes.

“Fad diets often lead people to fear carbohydrates. But the research continues to show that healthy carbohydrates — from fruits, vegetables, beans, and whole grains — are the healthiest fuel for our bodies,” said lead author Hana Kahleova, Director at the organisation.

In the study, published in the journal Nutrients, the team included nearly 100 participants for a 16-week randomised clinical trial and placed participants in either a plant-based, high-carbohydrate, low-fat diet group or asked them to maintain their current diet.

The plant-based diet group avoided all animal products and added oils and limited fat intake of 20-30 grams per day. There were no limits on calories or carbohydrate intake.

The control group maintained their current diets, which included meat and dairy products. Neither group altered their exercise routines.

The results demonstrated that total carbohydrate intake did not change in the control group, but increased significantly in the plant-based diet group, both as absolute intake and as a percentage of total calories.

At the end of the trial, body mass index, body weight, fat mass, visceral fat volume, and insulin resistance decreased significantly in the plant-based diet group. There were no significant changes in the control group, the researchers noted.

New blood test in pregnancy to predict autism risk in babies

New York, Sep 22: Researchers have developed a novel blood test for pregnant mothers that can, with nearly 90 per cent accuracy rate, predict the probability of having a child that will be diagnosed with autism.

According to studies, if a mother has previously had a child with autism, the risk of having a second child with the developmental disorder is approximately 18.7 per cent, whereas the risk in the general population is approximately 1.7 per cent.

In the study, led by Juergen Hahn, Professor at Rensselaer Polytechnic Institute in New York, metabolites of the folate-dependent transmethylation and transsulfuration biochemical pathways of pregnant mothers were measured to determine whether or not the risk of having a child with autism could be predicted by her metabolic profile.

Pregnant mothers who have had a child with autism before were separated into two groups based on the diagnosis of their child whether the child had autism or not.

Then these mothers were compared to a group of control mothers who have not had a child with autism before.

The results, appearing in the journal Research in Autism Spectrum Disorders, showed that while it is not possible to determine during a pregnancy if a child will be diagnosed with autism by age 3, they did find that differences in the plasma metabolites are indicative of the relative risk (18.7 per cent vs 1.7 per cent) for having a child with autism.

“These are exciting results as they hint at differences in some metabolic processes that potentially play a role in increasing the risk of having a child with autism,” Hahn said.

“However, it would be highly desirable if a prediction based upon physiological measurements could be made to determine which risk group a prospective mother falls into,” Hahn noted.

Eat fish thrice a week to boost your unborn’s eyesight, brain

London, Sep 21: Pregnant women can enhance the development of their unborn child’s eyesight and brain function by regularly eating fatty fish during the pregnancy, a new study has found.

The findings suggested that infants whose mothers ate fish three or more times a week during the last trimester of their pregnancy fared better than those whose mothers ate no fish or only up to two portions per week.

“The results of our study suggest that frequent fish consumption by pregnant women is of benefit for their unborn child’s development,” said lead author Kirsi Laitinen of the University of Turku in Finland.

“This may be attributable to long-chain polyunsaturated fatty acids within fish, but also due to other nutrients like vitamin D and E, which are also important for development,” Laitinen added.

For the study, published in the journal Pediatric Research, the research team analysed the results of a small group of mothers and their children drawn from a larger study.

The mothers had to keep a regular food diary during the course of their pregnancy. Fluctuations in their weight before and during pregnancy were taken into account, along with their blood sugar level and blood pressure.

The team recorded the levels of nutritional long-chain polyunsaturated fatty acid sources in the mother’s diet and blood serum, and the levels in the blood of their children by the age of one month.

Their children were further tested around their second birthday using pattern reversal visual evoked potentials (pVEP). This sensitive and accurate, non-invasive method is used to detect visual functioning and maturational changes occurring within a young child’s visual system.

“Our study therefore highlights the potential importance of subtle changes in the diet of healthy women with uncompromised pregnancies, beyond prematurity or nutritional deficiencies, in regulating infantile neurodevelopment,” Laitinen noted.
